The map by E.W. Gilbert “Pioneer Maps of Health” show where people died and the water pumps that were in the area. This information lead to the discovery of the pump that had cholera. The map could have shown where the people went to get water but using common sense we can see that people usually go to the one that is closer to their house. When I go look information the thing that I think matters most is the information. The way it is presented usually comes second in my opinion but if the information can be present in some sort of visual way of course I would prefer it.
